Does anyone know why you do mouth to mouth on someone?
You are breathing carbon dioxide into an unconscious persons' mouth, which stimulates the respiratory center in the brain to start working. In other words, the body senses too much carbon dioxide and wants to get rid of it, so it tells you to start breathing. Fascinating huh?
CLASS DISMISSED!

You are sooo smart! I think I learned that also, when we breathe not all of the oxygen is delivered to our cells so there is some O2 left that we breathe out, which helps the person you're helping:)
